Leachi eating less

As title reads, my 6 months old leachies not eating as usual recently.

I have been feeding them leachie linguine every other day(10% of their weight).

They used to eat as if someone cleaned the dish, but have been eating less than half.

It's very rainy season where I live and humidity level is kept over 70+ all day. (Temperature is well managed)

It might have affected them but not sure.

Should I be worrying them not eating well?
